Chemical Structure

Diisopentyl hydrogen phosphate CAS 3985-20-4 chemical structure

Description

Diisopentyl hydrogen phosphate (CAS 3985-20-4) is a high-purity analytical reference standard with the molecular formula C10H23O4P and a molecular weight of 238.26 g/mol.

Owing to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, Diisopentyl hydrogen phosphate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 238.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), Diisopentyl hydrogen phosphate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
